It works, but you can only download once per 2 hours unless you pay. would recommend "Easy Youtube Video Downloader Express by Dishita" (find by searching on addons.mozilla.org)

Does not work on youtube anymore.

hace unos días habilitó descargas en bilibili a 1080p. ahora solo de puede descargar a 480p. Solo queda valorar con la mínima.

won't let me add

This used to work well for me but not any more. Everything is marked "Download failed".
Everything.

Жадный помидоры!

Eskiden işe yarıyordu fakat güncellemeden sonra artık kullanılamaz hale geldi.

This plugin is now a scam, it redirects you to spam pay sites when you're trying to navigate media and it watermarks videos that download super slow. This isn't the plugin it used to be, it's now just scam ware. Avoid at all costs. I'm shocked that Mozilla doesn't remove this for violating TOS.

Puts an enormous QR Code watermark on the video for you to go pay them. It's not actually a free product.

скачивает только несколько видео и требует оплату. в описании владельцы обманывают не указывая это расширение как платное.

1 video every 2 hours, yet when I try to download audio only, nothing comes up.

The absolute irony of requiring a purchase to download a youtube video. trash.

When the extension was Version 9.x, it was wonderful! It worked as advertised, first time - every time. When the developer(s) upgraded the extension to Version 10.x, it became hit or miss as to when the extension would work. I now spend more time rerunning the extension to upload a movie or TV program and each time I get different results. I would dearly love to get Version 9.x back ... any improvements made by Version 10.x have been lost due to its functional inconsistency. When I sent emails, I was told that the problem is at my end and the extension works. (Were that so!) Please tell me how I can restore the extension to Version 9.x and I will upgrade my review. BTW, I am using Windows 10 and running the extension on FireFox.

I made a mozilla profile just to write this review. Puts a humongous watermark (easily 1/6th of the whole screen) on videos downloaded from youtube only and calls it "ensuring funding" and of course doesn't inform you of this anywhere before you actually use it.

To remove it, they want you to pay 20 bucks for what they advertise as a "lifetime license" that is of course valid until they decide this project isn't worth their time anymore, then your money is just oops gone. even the "privacy first" types are now making their programs worse to try and make you fork over your credit card.

The extension is a disaster. It worked perfectly for years and then in early 2026 they changed it. Every page has like 50 sources for a download, you can't tell which one is which, and almost none of them produce a working file.
